This module allows, with the use of python decorators, to transparently select a render function for an HTTP request handler's result. It uses mimeparse to parse the HTTP Accept header and select the best available representation.
Currently it only supports (web.py), but other web frameworks can be considered.
Code example:
import web
import json
from mimerender import mimerender
render_xml = lambda message: '<message>%s</message>'%message
render_json = lambda **args: json.dumps(args)
render_html = lambda message: '<html><body>%s</body></html>'%message
render_txt = lambda message: message
urls = (
'/(.*)', 'greet'
)
app = web.application(urls, globals())
class greet:
@mimerender(
default = 'html',
html = render_html,
xml = render_xml,
json = render_json,
txt = render_txt
)
def GET(self, name):
if not name:
name = 'world'
return {'message': 'Hello, ' + name + '!'}
if __name__ == "__main__":
app.run()Then you can do:
$ curl -H "Accept: application/html" localhost:8080/x
<html><body>Hello, x!</body></html>
$ curl -H "Accept: application/xml" localhost:8080/x
<message>Hello, x!</message>
$ curl -H "Accept: application/json" localhost:8080/x
{'message':'Hello, x!'}
$ curl -H "Accept: text/plain" localhost:8080/x
Hello, x!
